Question 116347
The first question has 5 choices, so 4/5 are wrong.  The second has 6 choices, so 5/6 are wrong.  We can assume the accuracy of one has no affect on the accuracy of the other, so we have two independent probabilities and can multiply for the combined probability.  (4/5)*(5/6)=(4*5)/(5*6)=20/30, or 2/3.
